Abstract

A new aerobic marine bacterium, strain S3431, was isolated from swab samples of an unidentified polychaete near Canal Concepción, Chile. This strain was thought to represent a new taxon within the genus . Although DNA–DNA reassociation values showed less than 70 % genomic DNA relatedness to established type strains, it shared 78 % DNA–DNA relatedness with DSM 15748 (=KMM 216) (Romanenko , 1994). has later been considered a heterotypic synonym of (Ivanova , 1998). Relatedness between strains S3431, DSM 15748 and the type strain LMG 12323 was therefore studied. Physiological traits and genomic information were shared at a high level by strains S3431 and DSM 15748, but not between these and LMG 12323. There was only approximately 20 % DNA–DNA relatedness between LMG 12323 and strains S3431 and DSM 15748. Based on the available phylogenetic and phenotypic data, the reclassification of DSM 15748 (Romanenko , 1995) → (Ivanova , 1998) as comb. nov. is proposed, and strain S3431 should be assigned to this new species. The name is proposed with KMM 216 (=DSM 15748=CIP 105339) as the type strain.
